Hello,
I have ovirt 3.3.2 running with FC19 nodes. I have several virtual
machines that use directly attached iSCSI LUNs. Discovering, attaching
and using new LUNs works without issues (vdsm needed some patching to
work with Dell Equallogic, as described here
https://sites.google.com/a/keele.ac.uk/partlycloudy/ovirt, but that's a
separate issue). Also live migration works well between hosts and the
LUNs get properly attached to the migration target host.
However, I don't see any way to disconnect/remove LUNs that are no
longer needed (e.g. VM is removed). What is the recommended way to
remove old LUNs, so that the underlying iSCSI sessions are disconnected?
Especially if a VM has been migrated between hosts, it leaves the LUNs
connected on multiple nodes.
Thank you in advance!
Best regards,
Boyan Tabakov

Hi Boyan,
Generally we don't disconnecting external Lun disks when we remove them
from the oVirt management.
You can disconnect them manually from the host, or use restart.
IIRC one reason for that, is because we might have Storage Domains which
use the same target.
another reason is that we keep those sessions, so it will be easier to
establish connection when reusing the target.
Regards,
Maor

Hi Maor,
Thanks for your explanation! I suppose we'll disconnect manually, if we=20
decide to use direct LUNs instead of Storage domain volumes (some=20
issues with SD volumes, as explained in another mail thread of mine).
Best regards,
Boyan
